Fragmenting projectiles: a case report and literature review of the G2 Radically Invasive Projectile

Innovations in projectile design present unique challenges for trauma surgeons when treating gunshot victims. The G2 Radically Invasive Projectile (G2 Research, Winder, Georgia, USA) (G2RIP) is a frangible, rapidly expanding bullet resulting in a distinct pattern of injury consisting of diffuse hemorrhage with multicavity trauma as well as unique radiographic features of the projectile. To efficiently manage patients injured by the G2RIP, trauma surgeons must be aware of these distinct characteristics, and of previous patterns in effective management such as liberal damage control and extensive use of CT. Understanding previous presentation and management of patients injured by the G2RIP can aid in improving patient care in the trauma center.

G2 Research Radically Invasive Projectile: The Importance of Recognizing Its Imaging and Autopsy Patterns

ABSTRACT

Many fragmenting and frangible projectiles have been developed in the course of firearm history. In addition, partially because of the concerns of range and environmental contamination, bullets constructed without lead have become increasingly common. A case regarding a unique projectile that incorporates both features, the G2 Research Radically Invasive Projectile ammunition, is discussed in this article. Here we report a 25-year-old woman who died of multiple gunshot wounds caused by G2 Research Radically Invasive Projectile ammunition. Because of the bullet's unique design, the wounds demonstrated characteristic radiographic patterns and unique autopsy findings. Familiarity with these findings is important to forensic pathologists in terms of case documentation, projectile recovery, and personal safety.

The G2 research R.I.P. fragmenting bullet-radiographic features of a recently encountered projectile

Gunshot wounds (GSWs) are an important cause of disability and death in the USA. Although radiography is limited in its ability to detect bullet types, a projectile introduced during the last decade, the R.I.P. bullet by G2 Research, consists of a base slug connected to 6 to 8 sharp trocars designed to diverge within soft tissue following impact, resulting in what we believe to be a unique imaging appearance that can be confusing to those not familiar with this particular projectile. Furthermore, this bullet is 100% copper, which may allow for safe imaging with magnetic resonance imaging if correctly identified prior to scanning.
